J'OGG'ER ATTACHMENT FOR PLATEN PRINTING-PRESSES.

Specification of Letters Patent.

Patented July 31, 1917.

Application filed April 3, 1917. Serial No. 159,433.

To all 'whom t may Concern Be it known that l, Lnwrs F. Howano, citizen of the United States, and a resident of West, in the county of McLennan and State of Texas, have invented a certain new and useful Improvement in Jogging Attachments for Platen Printing-Presses, of which the following is a specification.

@ne of the principal objects of my invention is to provide an automatic jogging attachment for platen presses, designed especially for use in connection with and on Chandler and Prices Gordon and New Se ries presses, of such construction as to be readily mounted directly upon the regular receiving board of the press and without the necessity of altering the press in the least.

Another object of the invention is to provide a jogger having improved means for comp actly and uniformly stacking the printed sheets, the jogging means being readily adjustable to accommodate sheets of various dimensions and being easily removable, whereby when it is not desired to use the jogger, a flat unobstructed surface for receiving the sheets will be presented.

Another object of the invention is to provide an improved jogging device which will be characterized by advantages of simplicity, durability, etiiciency in operation, and economy in manufacture and maintenance. "With these and other objects in view which will become apparent as the description proceeds, the invention resides in thel construction, combination, and arrangement of parts hereinafter more fully described and claimed, and' illustrated in the accompanying drawings in which like characters of reference indicate like parts throughout the several ligures, of which- Figure 1 represents a view in perspective of a jogging attachment constructed according to my invention;

Fig. 2 represents a top plan view thereof;

Fig. 3 represents a bottom plan view thereof;

Fig. at represents a View in section taken longitudinally on the plane indicatedv by the line Ll--i of Fig. l;

Fig. 5 represents a view in section taken on the plane indicated by the liney 5 5 of Fig'. 2;

Fig.l 6 represents a view in section taken on the plane indicated by the line 6 6 of Fig. 1.

in carrying my invention into practice, I provide a` base plate 5, which is substantially rectangular in configuration, and which is adapted to be secured directly upon the receiving' board ofthe printing press (not shown), through the medium of wood screws or otherv suitablel connecting means, indicated at t3. One corner of the plate, as at 7, is cutaway to accommodate a portion of the press. The under side of the base plate is formed with a marginal depending flange 8 braced by intersecting flanges or webs 9, as clearly shown in Fig. 8.

At what may be termed one of the rear corners of the plate is secured a bracket 10 including leg portions 11 countersunk at their inner ends into the base plate, and secured in position through the medium of screws or other suitable fastenings 12. The bracket is equipped with spaced parallel arms 13, one of which is offset beyond the adjacent edge of the base plate, and these arms rotatably support an oscillatory rock shaft la. The outer end of shaft 14, beyond the adjacent arm 13, carries a trip arm 15 extending aty right anglesto the rock shaft, and adjustable thereon through the medium of a set screw 16. On the other end of the rock shaft is arranged a depending arm 17, secured in position by means of a set screw 18, and through the lower end of the arm 17 the outer end of al link 19 extends. link connects the arm 17 with one of the guide rods 20, on which the jogging plates 21 are mounted. A spring 22 is coiled upon the rock shaft 14 intermediate the arms 13, and at one end engages a pin 23 carried by the arm 17, whereby to normally maintain this arm in such position that the guide rods 2O are at the outer extremities of their path of movement.

On the outer threaded end of the link 19 is mounted a nut 24 which screws into engagement with the lower end of arm 17, on one side thereof, and against the opposite side of the arm bears a spring 25 which is anchored against a transverse pin 26 carried by thy link 19` as clearly shown kin F l. l

These rods con erge tone rd each other7 and ai; heir adjacent ends are coupled "through the medium of pin and slot conneel'ions 30, each Willi one of lthe arms 3l of e three-arm lever which is pivoed on he under sine of J[he bese plaie adjacen*L the rear edge 'thereof; rEhe rod hns iis inner end ollset as at whereby to irojerlyv connech nii'h one of Jhe lever arms Bl.

The rods are so connected together Jdirongh the medium of the V three--armed lever, thai when the rod 2O is moved outwardly, the rods 2S and Q9 Will also he moved ouinferdly in sgf'nchronism with the rod 20, and to a distance equal "no Jdie distance to which rhe rod 2O is moved.

lmuclile will be at its highest point when il L, ihe i i n r nla es in posiiion their loner llO i 27 of llie hase CIO it strikes the trip arm," and hence theA latter will be raised about half an inch and then released. v Proper adjustment of the trip arm for bringingit into the correct position to be engaged by the knuckle may be had by loosening the se screw 1G and turning the arm into the desired position.

lli/Then the arm is raised, motion will be transmitted through the link 19 to the guide rod 20, andfrom this rod through the inedium of the three-arm. lever to the guide rods 28 and), whereby to effect the simultaneous movement ofthe guide rods inwardly whereby to bring the jogging plates into engagement 'with the stack of paper sheets. is soon as the trip arm is released by the knuckle, the spring acting against the arm li', will move the vlatter outwardly, thus causing a siinultaneous shifting movement of the guide rods outwardly7 and hence moving the jogging plates out of engagement with the stack ofV paper. The arm l will transmit its mot-ion to the link 19 through the medium of the spring 25, and hence the trip arm l5 may be adjusted so that the throw of the arm 1T will be relatively great, so that a relatively long pressure against the spring will be effected. This relatively long pressure will cause the jogging plates to more effectually perform their functions, by engaging with the stacked sieets of* paper a relatively longer time. At the same time, there will be no danger of the plate cutting or crimping the edges of stacked sheets. During the greater portion of Ithe time the jogging plates are out of contact with the stack of paper, thereby facilitating the operation of laying the sheets, one upon the other, as they are taken from the platen of the press, it being borne in mind t, at some point in the time occurring i iveen the delivery of successive sheets, the ging device isvactuated by the press for tigntening on the sheets of paper and making them settle into their proper position.

One of the material advantages of my invention the fact that it may readily be applied to a platen press without in the least mutilating the latter or altering or disarranging any of its parts. When the jogging plates are not to be used, they can rbe instantly removed, so that a substantially fiat unobstructed surface will be presented on which the sheets can be piled in the usual way. lf the operator so desires, he may, when the jogging plates are removed, shift the trip arm into such position as to be out of the path of the moving knuckle, so that the guide rods will not be operated by the press.

Although l have described the preferred embodiment of my invention, l may desire to make such changes in the construction, combination, and arrangement of parts thereof, 'as do noty depart from the spirit of the invention and the scope of the ap pended claims.
